22 January 2002. Thanks to Anonymous.
This is a singularly impressive compilation of the history of TEMPEST technology, the best we know of. Comments and additions welcome. Send to firstname.lastname@example.org
See related files and some of the documents cited: http://cryptome.org/nsa-tempest.htm
In particular see a different, more limited and complementary TEMPEST timeline:
This timeline was developed over a period of years, with the hope that it will be used to further the understanding of the subject. The data was gathered from unclassified sources, mostly web sites and books. Hopefully it tells an interesting story, even though it's far from complete. And, yes I realize, has a rumor or two thrown in as well. A lot of information I have gathered just couldn't be dated. I hope people will use the timeline to direct FOIA requests and other information gathering exercises on the topic. Acoustic TEMPEST information is mostly absent, as are military directives. This is obviously a work in progress. If so desired, you have permission to incorporate any/all parts of the timeline into your inherited TEMPEST pages.
Mid-1700s Ben Franklin conducts electricity.
1873 James Maxwell theorizes electromagnetic waves.
Late-1800s Crosstalk is frequent problem in infantile telephone system.
1914-1915 Field telephone crosstalk in World War I exploited and jamming attempted, leading to lower signal British Fuller phone.
1918 Herbert Yardley and the Black Chamber discover radio transmitter emanations.
No, Yardley and his people found that various electronic devices used to handle classified information emanated information, and that these emanations could be exploited to reconstruct the classified materials.
1919 Edward Hebern invents rotor cipher machine.
1925 Charles Francis Jenkins achieves first synchronized transmission of pictures/sound using 48 lines and mechanical scanning.
1927 Philo Farnsworth demonstrates electronic scanning.
1930s Allen Dumont develops cathode ray tube(CRT), eventually accepted as standard for electronic scanning.
1934 Communications Act gives equal opportunity to all to lawfully use electromagnetic spectrum. It establishes Federal Communications Commission(FCC); International Special Committee on Radio Interference(CISPR) formed to determine measurements and limits of radiation frequency(RF) emissions.
1935 IBM markets electronic typewriter.
1940s Receivers shielded for local oscillator radiation to prevent becoming beacons for enemy submarines in World War II.
1941 FCC authorizes black and white 525-line TV recommended by FCC-established National Television System Committee(NTSC).
1943 First working programmable electronic computer(Colossus) is built by British for breaking German High Command coding system.
1946 Canadian Communications Security Establishment(CSE) created, with communication security(COMSEC) its primary mission; British General Communications Headquarters(GCHQ) created.
1950s Berlin tunnel wiretaps by NATO discovered to contain plaintext signal on Communist teletype encrypted communications, first known example of HIJACK attack; Rand Corporation intensely studies shielding to prevent emanations.
1950 Chinese intelligence uses advanced acoustic techniques and materials against foreign embassies in Beijing.
1952 In a method similar to laser eavesdropping, KGB gets caught using great seal in American embassy as bug, a technique further researched by the KGB known as electromagnetic flooding method of interception. Technique also included using such unintentional emanators like ordinary light bulbs and electric circuits.
1953 FCC adopts RCA's color TV system; National Security Agency(NSA) formed, with signal intelligence(SIGINT) its primary mission; COMSEC declared national responsibility and COMSEC board is formed; intentional acoustic TEMPEST performed on Whirlwind I computer at MIT over phone line.

Mid-1950s U.S. Government becomes concerned about TEMPEST and establishes TEMPEST Program; Development of first TEMPEST standard - NAG-1A(General Non-COMSEC Publication); Television manufacturers work on EMF problems in set designs, especially in local oscillators. These problems are later exploited by British to enforce TV licenses.

It is not called a "HIJACK Attack", but should be properly called a "HIJACK Exploit", and since the Brits were not exploiting an intermodulation product the moniker of HIJACK does not apply. HIJACK is based on the mixing of two signals, the first signal (such as a cell phone) acting as a carrier for the secondary signal (typically classified materials).
1961 Julius Silverman et al. v. US (365 US 505) U.S. Supreme Court case concerns heating duct acoustic TEMPEST; British intelligence informs the CIA and NSA of Engulf and Stockade operations in conference. Presentation of Rafter to the CIA causes uproar.

1980s TEMPEST bugging devices built in UK go to places like Hong Kong golf club and Cambridge University; FBI shows example of TEMPEST information gathering to TRW because of PC radiation.
There is no such thing as a "TEMPEST Bugging Device", TEMPEST is dedicated to STOP compromising emanations, not exploiting them.
1980 NSA establishes its own internal TEMPEST security program; NACSIM 5002(Technical Rationale:Basis for Electromagnetic Compromising Emanations Limits) published. It is replaced by NSTISSAM/2-93.

Future revisions include Van Eck's actual plans; Ian Murphy (Captain Zap) presents TEMPEST receiver plans;
No, Captain Zap did not publish any such plans, but was only providing photocopies of van Ecks article and the Consumertronics raster analysis signal generator while unemployed and working as a taxi driver. Ian Murphy (Captain Zap) is and was a psychiatric patient and convicted felon with a long history of fraud and being delusionary. He has spent half his life either in prison or institutionalized.
First International Symposium on Electromagnetic Security for Information Protection(SEPI) takes place in Italy; 1989 British central computer and telecommunications agency publishes "TEMPEST:The Risk"; NSA drafts specification for high performance shielded enclosures.
Late-1980s French army demonstrates TEMPEST to French government.
Actually it was November of 1979 when they did the demo.
1990s After German reunification, removed French army sells 50 TEMPEST receivers at scrap value to unknown parties.
1990 British Computer Misuse Act explicitly excludes TEMPEST eavesdropping as threat and states that it is legal; Professor Erhard Moller of Acchen University in Germany publishes detailed update of Van Eck's work, with addition of helpful protective measures; "Computers and Security" journal publishes article by Peter Smulders of Eindhoven University of Technology on TEMPEST eavesdropping of RS-232 cable; Christopher Seline publishes evaluation of American laws, pertaining to TEMPEST, on Internet; National Security Telecommunications and Information Systems Security Committee (NSTISSC) TEMPEST Advisory Group (TAG) group formed to streamline national-level TEMPEST activities, which leads to updated standards; "EMP and TEMPEST Protection for Facilities" published by U.S. Army Corp of Engineers.

The above is a fantasy, all they did have the reconstruction of a composite video signal from a defective monitor. Anybody standing within 15 feet of the monitor could have seen the same information with the naked eye, and at no time was any confidential information obtained.
CIA Inspector General report galvanizes intelligence community to review and reduce domestic TEMPEST requirements. This leads to "smart" TEMPEST policy; National Security Telecommunications and Information Systems Security Advisory Memorandum (NSTISSAM)/1-91 (Compromising Emanations Laboratory Test Requirements, Electromagnetic) published. It is superseded by NSTISSAM/1-92; NSTISSAM/2-91 (Compromising Emanations Analysis Handbook) published; NSTISSAM/3-91 (Maintenance and Disposition of TEMPEST Equipment) published.

It was the FCC that harassed them, as they were trying to sell something to the public that didn't have the required FCC paperwork to cover it to ensure that it didn't cause interference to other radio devices. The product was so poorly built that is screwed up radio traffic at the local airports, and screwed up the ILS/Navigation systems at the runway.
1993 TEMPEST included as insidious tool of information warrior in book "Information Warfare" by Winn Schwartau; FBI tries TEMPEST techniques to help investigate CIA spy Aldrich Ames; Grady Ward publishes PC TEMPEST countermeasures, using easily-installed, widely-available components, on Internet; NSA introduces formal ZONE program through Government Industry TEMPEST Advisory Panel (GITAP); Worldwide market for CRTs reach 168 million units valued at $13.6 billion.

Winn's book was little more then clueless ramblings plagiarized from other authors who in turn had no idea what they were talking about. It is a classic case of the blind leading the blind who where then trying to pick the pockets of other blind people.
1994 "Redefining Security: A Report to the Secretary of Defense and the Director of Central Intelligence by the Joint Security Commission" recommends that domestic TEMPEST countermeasures no longer be required unless specific threat identified. Zoning solutions increase in importance; NSTISSI 7001 (NONSTOP Countermeasures) published; BEMA markets TEMPEST tents.
1995 Internet Underground magazine publishes article about TEMPEST capers in New York using DataScan device. After U.S. Army starts buying device, Pentagon requests that sales outside Army stop and it is agreed to;
The above is a total falsehood.

PGP 6.0.2 and Steganos II incorporate Soft TEMPEST fonts; James Atkinson claims Frank Jones and his Datascan device are a fraud, as are most other commercial devices.
Frank Jones is convicted in Federal Court of a serious felony, and in revenge attempts to launch a series harassment lawsuits which all get thrown out of court as being frivolous.

The ORNL was actually just based on the Micro-tel VDA-60, and the Kaiser RAS-515 raster analysis systems, both of which date from the early 80's.
2000 Appeal by John Young to NSA releases five more redacted TEMPEST documents; Freeware Windows text editor implements Soft TEMPEST fonts.
2001 In Kyllo v. US, U.S. Supreme Court rules against unwarranted infrared detection by law enforcement against private homes; Nine more redacted government TEMPEST documents are released.
2001 The Wall Street Journal runs a front page article on TEMPEST interception, and then is savaged for "shoddy journalism" by other media outlets when it is discovered that most of the article is complete fantasy. Frank Jones probation officer receives a severe reprimand from his superiors for overlooking multiple serious probation violations.
